Habits of the Mind

Lesson Plan in PDF (Grade Level: 4-9)

Uploaded: March 25, 2012

Study the relationships between two items to look into possible connections between items. Throughout history different cultures have looked to the sky for answers that may determine their survival and livelihood. Patterns in solar observations helped to determine crucial times such as when to plant and when to harvest the food to ensure the survival of the group. The first activity is designed to help make connections between events and the seasons of the year. One major connection relates the concept of the seasons to past observations. In the second activity, visualize the four key observation dates located in activity one, from a viewpoint in space looking down on the circle created. Look at the impact of the EArth's orbit around the Sun on seasons.

What can life tolerate? - Begins on page 37 To show that organisms living under extreme conditions on Earth can serve as analogs for extraterrestrial life. Activity 4 explores some of the reasons to think that extraterrestrial life is possible. In doing so, it draws on concepts developed earlier in the module such as understanding what life is, what it requires, and what makes a planet habitable.

It's Just Right: Extremophiles

URL (Grade Level: 4-6)

Uploaded: June 16, 2011

As scientists look for life elsewhere, we become more aware that life is tenacious and can survive in extreme environments. Some organisms on Earth can withstand extremes of temperature by shutting down their energy needs. In this activity, students set up an experiment to determine yeast’s temperature tolerance extremes. Students will put granules of yeast and sugar into containers. By varying the temperature of the water added and recording the amount of gas as demonstrated by the balloon inflation diameters, the students observe the relationship between temperature and metabolism.

Quantifying Changes in the Land Over TIme

Lesson Plan in PDF (Grade Level: 7-10)

Uploaded: June 15, 2011

Students learn to identify kinds of land cover (e.g., roads, fields, urban areas, and lakes) in Landsat satellite images. They decide which land cover types allow the passage of water into the soil (are pervious) and which types do not allow it (are impervious). They consider some effects of increasing impervious surface area on ecosystem health. Students then make land cover maps using two Landsat satellite images taken about a decade apart. They quantify the change of land cover from pervious to impervious surface during that time period. They make predictive maps of what they think the nature and extent of land cover change in the area will be in the year 2025, and speculate about the consequences for the availability of water for people and ecosystems. Students justify their predictive maps and their thoughts about the consequences of change in writing. This activity uses Landsat images of Phoenix, Arizona. Additional resources are available to permit teachers to download images of their regions through the USGS Web site provided in the resource section.
